Anti Corrosion and Concrete Protection for the Construction Industry

xist for treating rust problems in the most cost-effective, technologically advanced, efficient and reliable manner. From the construction industry to residential projects, there are solutions which provide on-site services including concrete protection, on-site blasting, and anti-corrosion solutions.

Rust and corrosion in construction

Rust and corrosion are the most common threats to any construction but with a bit of planning, the longevity of construction can be ensured. The main components of a building that suffer from corrosion and rust are, amongst others, metal beams and steel as well as the concrete itself. Corrosion is also an issue with limestone buildings. Whist this is generally gradual, it should also be taken into consideration.

Below we will introduce you to a few solutions to the most common rust and corrosion problems faced by the construction industry as well as go over some of the most important things to know in terms of anti corrosion coating, anti rust solutions and concrete reinforcement.

About Concrete Protection

Concrete repair services are designed to tackle concrete cracking, spalling, and their result: concrete failure. Reinforced concrete remains the most durable of building materials but it can also deteriorate because of a number of factors. Water is concrete’s number one enemy. Water can carry harmful chemical solutions into the concrete, bringing some of the surplus lime out, leading to efflorescence. Whilst efflorescence can occur in both natural and built environments, on porous construction materials it may present an outer cosmetic problem which can also indicate internal structural weaknesses. Concrete repair and refurbishment is available for commercial properties, housing, industrial facilities, roads and marine structures.

Anti Corrosion solutions for structural metal (Steel beams etc) used in construction

Corrosion protection of structural steelwork is quite straightforward if the factors affecting its durability are recognised. Steel structures that have survived the test of time under adverse conditions are many. Durable protective coatings are today available which, when appropriately used, reduce maintenance need and improve performance. The key to finding the most appropriate solution is in recognising the corrosive levels of the environment the structure is in and defining appropriate coating specifications. A steel structure that is exposed to a less than ideal environment, needs to be protected if its life is to be extended. Modern surface treatment technology can offer optimum protection treatment by combining good surface preparation, suitable coating, durability and minimum costs.

Anti-corrosion technology provides this unique tool to combat the effects of the environment, giving you the upper hand in dealing with corrosion. Such coatings protect structures from corrosion attacks, reducing repair, maintenance and replacement. These composites can be used to both rebuild corroded areas, and to provide repair that is strong and durable.

Removal of existing rust and preparing construction surfaces for protective coatings

It is well-known that the most important factor which determines the success of a corrosion protection system lies in surface preparation. Before applying any coating, surface preparation is the first stage in treating a steel substrate. A coating’s performance is determined by its ability to properly adhere to the surface. Grit blasting, or as the process is more commonly known, sandblasting, is used in the construction industry in Malta to both clean the steel and introduce a suitable surface for coating to be applied on.

Grit Blasting (Sandblasting) for the construction industry in Malta

In Malta, the term ‘sandblasting’ is commonly used to describe the removal of surface materials such as rust or paint. This reference is over-simplified as there exist much more advanced techniques that provide superior results with less mess and more cost effectiveness. Two options exist: metallic grit blasting as well as non-metallic grit blasting. This method is used in many industries, including in construction. It is also used in residential environments in terms of restoring iron works in balconies, farmhouses, as well as historical buildings.

Protective coatings to safeguard against rust and corrosion of buildings

Protective coatings to safeguard against rust and corrosion come in different forms. Paint coatings for steel structures usually comprise of a primer, intermediate/build coats, and finish coats. Each layer in this method has a specific function. After blast cleaning structural steelwork, refabrication primers are used so as to maintain the cleaned surface in a rust-free condition until the final painting can be done. The main conditions that affect anti rust paint coating application include temperature and humidity. Metallic coatings involve the application of metal coating to steel through four methods: hot-dip galvanizing, thermal spraying, electroplating and sherardizing. The latter two are used for fittings, fasteners and other small items, rather than structural steelwork.

Coating for structural steel

As the optimal material for steel fabrication and the construction of buildings, mechanical equipment and other structures, the life-span of structural steel can be easily extended with corrosion resistant primers and coatings. Anti-corrosion services for concrete plants and structural steel must ensure that their coatings meet the environmental demands in which the structure lies. Such coatings provide long term protection for structural steel, hence leading to steel reinforcement.

Chemical Resistance coating for pits and similar applications

The presence of environmental and industrial chemicals demand that a coating is safe and consistent in function. Chemical resistant coatings offer many advantages including: chemical resistance; corrosion resistance; abrasion resistance; durability; lubricating properties and easier clean up.

Spray painting of exteriors for protection and aesthetic appeal

Weather conditions, moisture, and prolonged sun exposure all take their toll on exteriors. On-site or in a controlled setting, a large selection of spray painting services are available. These include: electrostatic, airless, air assisted and conventional spray painting. In the construction industry, high quality spray painting services can be provided according to specific need.

Protection for concrete plants and construction equipment

Concrete plant corrosion protection
Besides protecting new buildings and construction components there is much that can be done to ensure the longevity of construction equipment. Equipment such as cranes, concrete mixers, stone chippers and many other pieces of specialized equipment can benefit from protection against rust and corrosion. Not only will this aid in efficiency, it also substantially reduces maintenance costs in the long-run.

Anti Corrosion & Rust Protection for industrial vehicles

Making use of appropriate rust protection for parts and vehicles ensures that costly repairs are kept to a minimum and that your vehicle’s metal body does not wear out easily. Industrial vehicles constitute a big purchase for any company; ensuring their reliability, appearance and performance is hence a must. In terms of resale, any sign of rust will have a negative impact on the resale price. Resources to adequately protect your capital investment are available.
